A plant-based intoxicant that the former Starfleet officer Raffi Musiker smokes through a vaporiser during her years of isolation at Vasquez Rocks in Star Trek: Picard.
Snakeleaf is a recreational drug derived from a plant. It appears in the first season of Star Trek: Picard, set in 2399.
Raffaela Musiker was Picard's first officer during the Romulan evacuation and lost her career when he resigned. Fourteen years later, in The End Is the Beginning, he finds her living alone in a cabin at Vasquez Rocks, vaping snakeleaf and drinking while she pursues her theories about the attack on Mars. She continues to use it aboard Rios's ship La Sirena, particularly after a painful reunion with her estranged son.
The habit is part of the series' portrait of a Federation in which a brilliant officer can be left to drift, and Raffi's struggle with addiction continues into later seasons.
